<p>PURPOSE: To improve gas dissolving efficiency by providing a depressurizing mechanism on the downstream side of a pressurized gas dissolving mechanism for bringing a pressurized liq. into contact with a pressurized gas to dissolv the gas in liq. and using the depressurizing mechanism to depressurize the liq. by passing the pressurized liq. through plural capillaries. CONSTITUTION: In a gas dissolver 19, a raw liq. 7 to dissolve a gas is passed through a flow control valve 8 and introduced into the liq. inlet 10 of the membrane-type gas dissolving mechanism 9 into which a pressurized gas 15 is introduced from a gas inlet 14. In the dissolving mechanism 9, the gas flows along the outside of a hollow yarn membrane, a part of the gas is passed through the membrane and dissolved in the liq., and the remaining gas is discharged from an outlet 16. The liq,. leaving the mechanism 9 from a liq. outlet 11 is introduced into a depressurizing mechanism 12 from its inlet 4, depressurized and then discharged into the atmosphere from an outlet 6 as a gas dissolving liq. 13. The liq. is passed through the plural capillaries formed by melt spinning in the membrane 12 and depressurized.</p> |
